Spatial excavator with dual-mobility movable arm, dual-mobility bucket rod and single-mobility bucket

Abstract

A spatial excavator with a dual-mobility movable arm, a dual-mobility bucket rod and a single-mobility bucket comprises a two-dimensional rotating arm mechanism, a two-dimensional rotating bucket rod mechanism and a one-dimensional rotating bucket mechanism, wherein the two-dimensional rotating arm mechanism comprises a two-dimensional rotating arm, a first hydraulic cylinder and a second hydraulic cylinder; the two-dimensional rotating bucket rod mechanism comprises a two-dimensional rotating bucket rod, a third hydraulic cylinder and a fourth hydraulic cylinder; and the one-dimensional rotating bucket mechanism comprises a one-dimensional rotating bucket, a fifth hydraulic cylinder, a first link and a second link. The movable arm and the bucket rod of the novel excavator both are capable of performing independent spatial two-dimensional rotation; the whole excavator is capable of performing spatial quintuple-mobility motion, and is flexible in mechanism output track, large in working space and high in working efficiency; and the spatial excavator is capable of playing a good role in construction sites with severe environment and narrow space and emergency accident rescue sites needing quick excavation, barrier clearance and flattening.

Description

Technical field [0001] The invention relates to the field of excavators, in particular to a space excavator with a two-movement boom, two-movement stick and one-movement bucket. Background technique [0002] Hydraulic excavators are widely used in mechanized construction such as industry, transportation, energy, farmland transformation, water conservancy, civil construction, mining, and modern military engineering due to their simple structure, light weight, and more complex actions. The traditional hydraulic excavator realizes the trajectory output of the bucket root on the plane through the joint drive of the boom hydraulic cylinder and the stick hydraulic cylinder, and then is driven by a separate bucket hydraulic cylinder to realize the bucket turning. However, due to its structural limitations, the actuator of this type of hydraulic excavator can only achieve the trajectory output of two-dimensional translation and one-dimensional rotation of the bucket in its working plane....

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a space excavator with two movable arms, two movable rods and one movable bucket, which can effectively solve the problem that the traditional plane hydraulic excavator can only realize the trajectory output in the plane, resulting in inflexible movements and limited working space. Limited, low work efficiency and other issues
